Codex
Codex is an OpenAI code-focused language model designed to understand and generate computer programs from natural-language and code inputs.
Introduction to Generative AI, Second Edition
An OpenAI GPT-based language model fine-tuned to generate and understand computer code.
- How it is used
- Supports programming as a pair-programming aid for autocomplete, code generation, and developer productivity.
- How deep it goes
- Explains fine-tuning, common interactions, and productivity uses, but stops short of model implementation and detailed failure analysis.
- Examples
- Uses Copilot suggestions, comment-to-code conversion, testing, coding interviews, and non-native English assistance.
- What you can do after
- Apply it via GitHub Copilot for autocomplete and first-draft functions while retaining human review.

Generative AI in Action
Codex is a language model trained particularly on source code to generate and assist with programming code.
- How it is used
- Supports code generation, completion, legacy-code understanding, and unit-test generation within developer workflows.
- How deep it goes
- Explains training, language coverage, contextual prompting, and fill-in-the-middle completion, but stops short of model internals.
- Examples
- Uses Copilot completions, contextual code suggestions, legacy-code assistance, and unit-test generation as concrete applications.
- What you can do after
- Apply it via GitHub Copilot to generate code and complete programming tasks across multiple languages.
